This device crawls at the moment. The rear wheels are, for now, freewheeling so they’re dragged. Imagining the front ‘whiskas’ additionally detecting something or other as they sweep from side to side.
It is a hacked DFrobot Insectbot. Yellow washers are ballast (big buggy ‘eyes’ are sensors).
No software updates just yet so it still has basic obstacle avoidance.
Learning about traction, locomotion etc though trying not to reinvent the wheel! Motorised wheels may be interesting?
Right now “Necessity” is pretty dumb but it’s a good vehicle (pun intended) for learning and experimentation.
